A newly published study examined the risk of asthma in children exposed to passive tobacco smoke. Researchers analyzed National Health and Nutrition Examination Survey (NHANES) data collected from 2003 to 2014 (n = 8064).

Findings included:

  • The proportion of children living with household smokers decreased from 24.9% in the 2003-2004 cycle to 11.4% in the 2013-2014 cycle.
  • Highly exposed asthmatic children were primarily Non-Hispanic Black and whose family incomes were below poverty guidelines.
  • Overall results reveal passive smoke exposure level among children ages 3-11 in the US decreased over the study period.
  • Nevertheless, higher exposure to passive smoke is still associated with higher odds of childhood asthma.

 

The researchers concluded that targeted smoking cessation interventions in clinical practices are needed to reduce tobacco smoke exposure and related asthma risk in children, particularly in low-income and minority groups.
